When several occurrences of the same function are available in
the IED, they are referred to as instances of that function. One
instance of a function is identical to another of the same kind but
has a different number in the IED user interfaces. The word
"instance" is sometimes defined as an item of information that is
representative of a type. In the same way an instance of a
function in the IED is representative of a type of function.
1. Internet protocol. The network layer for the TCP/IP protocol
suite widely used on Ethernet networks. IP is a connectionless,
best-effort packet-switching protocol. It provides packet
routing, fragmentation and reassembly through the data link
layer.
2. Ingression protection, according to IEC standard
Ingression protection, according to IEC standard, level
IP20- Protected against solid foreign objects of12.5mm
diameter and greater.
Ingression protection, according to IEC standard, level IP40-
Protected against solid foreign objects of 1mm diameter and
greater.
Ingression protection, according to IEC standard, level
IP54-Dust-protected,protected against splashing water.
